HYDRAULIC BRICK-PRESS.

SPECIFICATION forming part of Letters Patent No; 570,314, dated October27', 1896.

Application filed December 26, l 895. Serial No. 573,270. (No model.)

To all whom it may (JO/7106772,:

Be it known that I, GOTTHOLD LANGER, a citizen of the United States,residing at St. Louis, State of Missouri, have invented certain new anduseful Improvements in I-Iydraulic Brick-Presses, of which the followingis a full, clear, and exact description, reference being had to theaccompanying drawings, forming a part hereof.

Myinvention has relation to improvements in hydraulic bllCl pl6SS6S; andit consists in the novel arrangement and combination of parts more fullyset forth in the specification and pointed out in the claims.

In the drawings, Figure l is a middle vertical section on the line 00 a:of Fig. 2, showing some of the parts in elevation. Fig. 2 is a rear viewof the machine. Fig. 3 is a top plan view. Fig. 4: is a plan view ofone-half of the lower compression-head controlled by the upper piston.Fig. 5 is'a plan view of onehalf of the upper compression-headcontrolled by the lower piston. Fig. 6 is a front elevation of themachine. Fig. 7 is a section on the line i y of Fig. 1 as to its upperportion, the lower portion of said figure being in elevation. Figs. 8,9, 10, and 11 are sections of the main controlling-valve, showing thefour positions assumed by the same during a single operation of theoperating -pistons. Fig. 12 is a side elevation of the valve in theposition indicated in Fig. 11, and Fig. 13 is a section on line 2 a ofFig. 6.

The object of my invention is to construct a hydraulic press, designedespecially for the manufacture of bricks, which shall combine simplicityof construction with a maximum mechanical efficiency, the latter beingmore or less dependent on the specific construction of the valvecontrolling the flowof water to the operating-pistons and on themechanism by which the valve itself is manipulated. The eificiency inthe present instance too is dependent on the permanent head or pressurestored-in the air-compression chamber and on. the specific relation saidchamber bears to the valve above referred to.

In detail the machine may be described as follows:

Referring to the drawings, 1 represents the main water-supply tank, fromeither side of piston cylinder 22.

the bottom of which lead the conducting-pipes 2 2, each pipe being incommunication with a pump 3. A suitable check-valve of the usualconstruction is interposed in the path of each pipe near its juncturewith the pump, the casing 4 only of such valve being here shown. Eachpump 3 is securely bolted by means of a flange 5 to the under side of abedplate 0, which serves as a supporting-plate for the several parts tobe presently described. The piston-rod 7 of each pump operates within astuffing-box capped by a terminal bolt 8 above the bed-plate, the pumpsbeing operated through the medium of the connectingrods 9, driven by thecrank-arms 10 at either end of the transverse shaft 11, mounted insuitable bearings 12 on top of the bed-plate, the shaft itself beingdriven from the pulleys 13 at each end thereof by any convenient orsuitable source of power. The discharge end of each pump is providedwith a suitable check-valve, of which only the casing 14E is shown, andcommunicates by a pipe connection 15 with the bottom of anair-compression chamber 16, located at one end of the bedplate 6;

Passing through suitable stuffing-boxes 17, formed in the oppositelateral walls of the aircompression chamber 16, and closed at its outerend, is a hollow rotatable tube or conduit 18, having a series ofperipheral slots 19, establishing communication between the chamber andthe interior of the tube, said tube being disposed substantially atright angles to the shaft 11 and being supported at its opposite end inthe stuffing-box 20, carried by the outer Wall of a valve-casing 21,which latter forms a lateral extension or enlargement of the main Theexpanded end or flange 23 of the tube 18 forms one end of acontrolling-valve 24, operating within the valve-casing 21 and forming,preferably, an integral part of said tube, the opposite end or base ofthe valve finding a seat within a suitable circular depression or socket25, formed on the inner wall 26 of the valve-casing 21.

Leading from the valve-casin g are two passages 27 28, establishingcommunication, respectively, with thebase andmiddleof the main cylinder22, and leading from thevalvecasing is also a discharge-pipe 29, whichcominunicates with the main supply-tank l. The passages 27 28 and thepipe 29 are controlled by the various ports and groove whichcharacterize the controlling-valve 24, whose action will hereinafter bespecifically described.

Reciprocating within the main cylinder 22 are two pistons, a lowerpiston 30 and an upper piston 31, the lower having a piston-rod 32,passing through a stuffing-box at the base of the cylinder-plate 33,(which, by the way, is lapped and connected to the bed-plate (5, wherebyboth forma solid and continuous bed-plate,) the lower end of thepiston-rod 32 carrying a head 34, provided with a plunger 35, of usualconstruction. The ends of the head 34 partially embrace the stationarypillars 36 of the machine-frame, said pillars serving thus to guide thehead in its reciprocation. The upper surface of the cylindrical piston31. is secured directly to or forms an integral part of the transversebeam 37, from the outer ends of which depend the reciprocating rods 38,by which the lower head 39 and plunger 40, forming part thereof, areoperated. The ends of the head 39 also partially embrace the pillars 36,thus guiding the head in its reciprocations. (See Figs. 4 and 5.) Therods 38 pass through suitable lugs 41 of the head 39 and terminate insuitable expanded ends 42, by which the head is raised as the rods 38and piston 31 ascend or rise.

The mold-box frame 43 is secured between and keyed to the pillars 36,the reciprocating rods 38 passing loosely through the guide- Ways formedby the grooves 44 of the frame and corresponding grooves 45 of theterminal guide-plates 46, secured to said frame. The frame is providedwith a groove 47 for the reception of the tongue 48, forming a part ofthe mold-box 49, by which the mold-box can be conveniently slipped intothe frame. A plate 50 reinforces the frame on the side from which themold-box is introduced.

The mold-box can contain any number of compartments 51, each beingdesigned, of course, to receive a plunger 35 from the top and a plunger40 from the bot-tom, a suitable plate 52, secured to each plunger 40,being introduced into each compartment for the support of the clay fedthereto from the hopper 53, as subsequently explained. The thickness ofthe brick and the degree of compression of the same is regulated byvarying the initial position of the head 39. The latter is provided withan inclined supporting-block 54, which rests on a correspondinglywedgeshaped or inclined block 55, the latter being adapted to beadjusted back and forth by the screw 56, operated by a hand-wheel 57, asuitable grooved plate 58 serving to guide the block in its adjustments.It is apparent that as the block 55 is moved in one direction or theother it will vary the relative position of the head 39 and plunger 40,carried by it, and hence determine the capacity of the resultingcompartments 51, within which the clay is to be compressed.

It has been stated that power is imparted to the transverse shaft 11. Itwill now be in order to describe the means whereby the ro' tatable tube18 is set in motion and how this operates the valve 24, controlling thepassages 27 28 and the opening leading to the pipe 29.

Carried by the shaft 11 is a worm-pinion 59,whicl1 meshes with aworm-wheel 60, keyed to a longitudinal shaft 61, mounted in bearings 6263 of the compression-chamber 16 and cylinder 22, respectively, the saidshaft 61 having additionally keyed thereto a differential or compoundcam-plate 64, revolving with the shaft in the direction indicated by thearrow in Fig. 7, the several sections of the camplate corresponding todifferent positions assumed by the valve 24 under the operation of saidsections. sections a b c d, each formed by the arc of a circle ofdifferent radial lengths, the maximum radius identifying the section b,the next smaller, section a, the next, section 0, and the smallest,section (Z. The several sections are connected by rounded shoulders 65,by which the parts operating the tube 18 are driven.

Mounted in suitable bearings or standards 66 67 on top of the bed-plateand adapted to reciprocate therein in a direction parallel to the planeof rotation of the cam-plate 64 is a rack-bar 68, hearing anantifriction-roller (39 along its upper surface. As the cam-plate 64rotates in the direction indicated the shoulders successively come incontact with said roller and shove the rack-bar in its bearings in onedirection. From the peculiar formation of the cam-plate, however, thebar (38 will be shoved forward only by two of the shoulders 65viz., thetwo between the sections d and a and a and b, and the distance it isthus shoved forward will be equal to the difference in length betweenthe radii of sections (Z and CL and a and b. Of course, while the roller69 is being traversed by the arc of any section no further movement oradvance for the time being of the rack-bar will take place, that is tosay, the rack-bar will be sta tionary for the interval that the are ofany section is passing over the roller 09.

Referring to Fig. 7, We see that the arc of section a is passing overthe roller 69. The rack-bar is stationary, therefore, until it is shovedor advanced by the shoulder between sections a and b, and the amount ofadvance will be the difference in length between the radii of sections aand b. The shoulders 65 between the sections 1) c and c d are, however,inoperative so far as advancing the The cam-plate has four rack-bar isconcerned, since, after the section plate (that is, the shouldersbetween the sections cl a and a b) it is returned or reciprocated to itsoriginal position by the pinion 7O cooperating with the rack-bar, saidpinion being mounted in the standard 67 and being controlled by aresilient coiled spring 71, having one end secured to the shaft of thepinion and the other end to the inner wall of a casing 72, forming apart of the standard 67. (See Fig. 6.) The spring 71 is wound so thatits tendency is to constantly tend to turn the pinion 70 in a directionto move the rack-bar against the impelling or advancing action of thecam-plate 64, by which action the roller 69 is always kept in closecontact with the periphery of said cam-plate, thus insuring a positivereturn of the rack-bar to its original position as the roller 69 ispassing over the releasing-shoulders 65, separating the sections 6 c and0 cl, the term releasing being applied here for convenience to thelastnamed shoulders,which do not positively advance the rack-bar, butwhich (on account of the gradually-decreasing length of the radii of thesections between which theyare interposed) permit its return to itsoriginal position under the action of the coiled spring 71.

From the foregoing it is therefore obvious that the rack-bar 68 isreciprocated back and forth during the operation of the machine in onedirection by the impelling-shoulders of the cam-plate and in theopposite direction by the action of the coiled spring 71. As therack-bar thus reciprocates, the teeth thereof cooperate with a toothedsegmental gearwheel 7 3, embracing and secured to the tube 18. The tube18 will therefore rock back and forth in its stufl'ing-boxes under thereciprocating action of the rack-bar. As the tube is thus oscillated itcorrespondingly oscillates the valve 24, carried by the inner endthereof, placing the ports of said valve in a newrelation with referenceto the passages 27 28 and pipe 29 for every advance of the rack-bar,that is,with every advance of the several sections of the cam plate 64.The valve 24, which is cylindrical, is composed of two ports 74 75,communicating with the tube 18, and a peripheral groove 76, adapted toestablish communication between either of the pastime to describe theoperations of the machine under the several positions of said valve.

Starting with the position of the valve as shown in Fig. 8, in whichposition it corresponds to the position of the earn-plate as its sectiona is passing over the roller 69, we see that ports 74 75 arerespectively in communication with the passages 27 28, leading to thecylinder 22, and that communication with the pipe 29 is cut off. Underthese circumstances the water passing through the tube 18 enters thecylinder 22 on bothsides of the lower piston 30 and below the piston 31.\Vater being thus introduced on both sides of the piston 30, and thepressure being thus equalized, the said piston 30, with its piston-rod32, will immediately drop by its own weight under the action of gravity,carrying the head 31 and plungers 35 to the mold-box. The heavy upperpiston 31 under these circumstances remains stationary, but should itfor any reason rise slightly, (which it might do if the lower piston didnot drop fast enough under the circumstances and thus allow an undueaccumulation of pressure under the upper piston,) and draw after it therods 38, depending from the crossbeam 87, carried by the same, I leavesufficient play between the lugs 41 and the ex panded end 12, so thateven should the upper piston rise slightly it would not raise the head39 and plungers 4:0 with it and disturb the contents of the compartmentsof the mold-box. As the cam-plate 64 continues its rotation in thedirection previously indicated the shoulder 65 between the sections aand I) advances the rack-bar 68 a distance equal to the differencebetween the radii of the arcs of said sections, rocking the tube 18 andturning the valve 24 to the position indicated ICO in Fig. 9, andestablishing communication between the tube 18 and the passage 28 only,and further establishing communication between the passage 27 andwaste-pipe 29 by means of the groove 76. Under these circumstances thewater from the air-compression chamber 16 is forced through the passage28 into the cylinder 22 between the tWo pistons only, forcing thepistons positively apart and driving the water below the lower pistonthrough the passage 27 groove 76, and waste-pipe 29 into the supply-tank1., As the pistons 30 and 31 are thus forced positively apart theplungers 35 and 40 will be driven into their respective compartments ofthe mold-box, the two sets of plungers as a result compressing the claycontained in the mold-box compartments. With the further rotation of thecam-plate 64 the section c will be the next to bear against the roller69; but as the radius of the arc of said section is much less than thatof section I) just passed the irnpelling action of the cam-plate ceases,and the spring 71 will now retract the rackbar 68, rocking the tube 18and the valve 24 to the position indicated in Fig. 10, that is to say,water will be forced only under the lower piston 30 through the passage27, communication being entirely out off between the port 75 and passage28, and that between the latter and the pipe 29 being also cut off, withthe exception of the slight relief-opening afforded by the extension 76of the groove 76, to be presently referred to more in detail. From theprevious operation, however, the space in the cylinder 22 between thetwo pistons has already been filled with water, thus forming a solidconnection, as it were, between the two pistons. It follows, therefore,that as water is forced under the lower piston 80 for the third positionof the valve 2 said water-pressure will raise both pistonssimultaneously, thus simultaneously elevating the plungers 35 40,between which the brick has been compressed and is still held, the partsbeing so proportioned that no further simultaneous elevation of saidplungers will take place after the plungers 40 have passed through themold-box compartments and the upper surfaces of the plates 52 havebecome flush with the upper surface of the mold-box, by which time ofcourse the bricks have been fully lifted or ejected from the mold-box,although still held between the two sets of plungers by which they werecompressed. As the cam-plate 6 f continues its rotation, and thesection, d, having the shortest radius is brought against the roller(39, the spring 71 has by this time retracted the rack-bar 68 to thelimit of its backward stroke and the tube 18 and valve 24 have beenturned to the position indicated in Fig. 11; that is to say,communication has been cut off between the port '75 of the valve and thepassage 28, but communication has been established between the passages27 2S and discharge-pipe 29 by means of the port 74 and the groove 7 0,respectively, whereby the water from between the two pistons runs backinto the tank 1 through the groove 76, allowing the upper piston to dropto its normal position, and the water from the chamber 16 passes throughthe port 74, a portion passing through the passage 27 below the piston30 and a minor portion being directed through the port '74: into thepipe 29, so as to partially reduce the pressure of the water enteringbelow the piston 30 and prevent a raising of the latter faster thanthewater above it can return to the tank and allow the upper piston todrop to its normal position. The instant the upper piston 31 begins todrop and the lower one to rise a sufficient release of the bricks heldbetween the plungers 35 is effected to enable the end of the charger 77at that instant toshove them aside from between the plungers, the

' action of the charger being hereinafter more fully described. Thevalve 24 therefore has by this time been brought to its normal or fourthposition and the cam -plate (Mhas made a complete revolution; that is,the four sections at h c 01 thereof have all acted on the roller 69 ofthe rack-bar, the sections a b driving said bar in one direction and theradially receding sections 0 d releasing said bar and allowing it to bereciprocated in the opposite direction through the action of the spring71.

Of course as the advancing shoulder of the section a strikes the roller69 in the beginning of the next. succeeding revolution of the cam-platethe bar 68 will be shifted so as to turn the valve 2i to the positionindicated in Fig. 8, thus beginning the next cycle of operations.

It was stated above that the moment the bricks between the plungers arereleased during the fourth position of the valve (the release being infact effected by an initial slight raising of the lower piston beforethe upper piston begins to drop and lower its ejectingplungers below theupper surface of the moldbox) the charger shoves the bricks aside. It isnow in order to describe the operation of the charger and how it feedsthe clay to the mold-box at the same time that it shoves the bricksaside which have been formed during the previous operation.

Carried at the outer extremity of the shaft 61, to which are keyed theworm-gear 00 and cam-plate 64, is a terminal eccentric disk 78, providedwith a cam-guideway 7 9 on its outer face, the said guideway beingadapted to receive the antifriction-roller 80, carried at the inner endof a pin 81, secured to the upper end of a rod 82, adapted toreciprocate with in a bearing or bracket 83, secured to the outer wallof the compression-chamber 16. Pivotally connected to the lower end ofthe reciprocating rod 82 is one end of a link 84, whose opposite orlower end is pivoted to the free end of the arm 85, connected rigidly toa rock-shaft 86 intermediate of its ends, said rock-shaft being mountedin suitable bearin gs or brackets 87 at the end of the bed-plate 6. Theouter projecting ends of the rockshaft 86 have each secured thereto arigid arm 88, to whose lower end is pivotally secured one end of a link89, whose opposite end is pivotally secured to the charger 77,previously referred to. The charger 77 is mounted on rollers 90, movingin a suitable track 91, and has a hollow compartment 92 for thereception of the clay dropped into it from the hopper It is apparentthat as the shaft 61 rotates the disk 78 will impart a reciprocatingmotion to the rod 82, which in turn will oscillate the rock-shaft 86,and the latter will, through the connections 88 and 89, impart areciprocating motion to the charger 77, causing the latter at the propermoment to deposit the necessary quantity of clay into the compartmentsof the mold-box and at the same time to shove aside the compressedbricks released by the separation of the plungers 40 during the fourthposition of the controlling-valve 24, as already explained. The hopper53 is supplied with clay from the inclined chutes 93, to which it is fedfrom any convenient source.

As motion is imparted to the transverse shaft 11 and the pumps 3 areoperated the space in the chamber 16 is filled with water to such anextent until the air confined within the chamber is under great pressureand compressed into a small volume. The expansive force of the confinedair is utilized to positively force the water pumped into said chamberinto and through the rotatable or oscillating tube 18 and the valve 2%carried by it,

thereby making under this reserve of pressure the pistons 30 and 31instantly responsive to each and every position or condition of thevalve. The specific construction and details of the present machine makethe latter compact and yet at the same time effective and capable ofdeveloping a maximum amount of mechanical efficiency. The valve, too, inthe present case having a broad seating-surface and being subjected onlyto an oscillatory or rocking motion, there islittle liability of leakageor of the parts getting out of order.

It is to be understood, of course, that the present device, or ratherthe hydraulic feature of it, is not necessarily restricted tobrick-presses, but may be utilized for hydraulic purposes generally.Under the present construction a single valve operates two pistonsconfined in a single cylinder, the valve itself being controlled by thehollow tube which communicates with the compres sion or air chamber, inwhich the water is always under great pressure.

9i represents relief-ports for the chamber 1 6.

It will be seen that the end of the tube 18 which is mounted in theouter stuifing-box of the chamber 16 is closed, the inner wall of theclosed end serving to take up or resist the pressure necessarilycommunicated to the interior of the tube from said chamber. This sameinterior pressure in the tube is resisted at its opposite end by theinner surface of the base of the valve 24. The hydraulic pressures beingthus equalized within the tube at either end, no excess of pressureremains to force the valve 24 against its seat, and said valve thusoscillates on its seat without friction. Vere the tube 18 merely of alength to be supported by the inner stuffing-box of the chamber 16, andwere the tube under those circumstances to open directly into thechamber 16,the pressure within said chamber would be communicated to theinterior of the tube, but at thesame time would force the valve againstits seat with a force equal to that which would be communicated to thesuperficial area of the exposed surface of the base of the valve and thelatter would operate under great friction. -By the present arrangement,however, all friction incident to the hydraulic pressure disappears.

A reference to the drawings, Figs. 8 to 11, inclusive, discloses thepresence of an exten sion 7 6 to the groove 76 of the valve 24. Theobject of said extension is to establish a sufficient leakage from thespace between the two pistons :30 and 31 during the third position ofthe valve, Fig, 10, whereby, as the two pistons and their plungers areraised simultaneously to effect the discharge of the compressed brickfrom the mold-box, the upper piston with its plunger may take a slightdrop to relieve the strain from the brick to which it was subjectedduring the compressing operation and prevent the unsupported sides ofthe brick from crumbling under the said strain after the brick has beenraised from the mold-box.
